HOISTING A ND TRANSFER RING 'MECHANISM.

SPECIFICATION forming part of Letters Patent No. 768,015, dated August 16, 1904.

Application filed August 17,1903- To all whom it may concern:

Be it known that 1, CHARLES A. MORRIS, a citizen of the United States, residing at Glenridge, in the county of Essex .and State of New Jersey, have invented certain new and useful Improvements in Hoisting and Transferring Mechanisms, of which the following is a specification.

This invention relates to the class of devices adapted in the main for hoisting a load and transferring it to another point and also to devices for transferring a load by trolley without necessarily elevating it; and the object of the invention is to provide means for storing upv energy or power in some form while handling the load, to be utilized afterward for returning the trolley to the receiving-point whenthe latter is'relieved of its load.

In the accompanying drawings, which serve to illustrate certain embodiments of the invention, Figures 1 and 2 are views designed to illustrate the principles involved in the mechanism, the former showing the trolley at the receiving-point at outer end of its track and the latter showing it at the dischargingpoint at inner end of the track. Fig. 3 illustrates the mechanism as applied for hoisting and transferring freight, the hoist being at the lifting or outer end "of'the track-beam; and Fig. 1 is a similar view showing a reverse arrangement where the load is-hoisted at the opposite or inner end of the track-beam. Fig. 5 is a detail view of the friction-brake. Fig. 6 is a detail view of a trolley. Fig. 7 is aview illustrating an application of the invention to the storing up of energy for returning an empty trolley under conditions where the load is not primarily hoisted. Fig. 8 is a detail view of the trolley employed in the construction of Fig. 7.

Referring, primarily, to Figs. 1 and 2, 1 is a track-beam suspended at one end, called here the inner end, from apoint w and suspended at the other or outer'end from a point 3/ by tackle 2, one end of the fall 2 of said tackle being attached to a trolley 3 or the like, which runs on the track-beam. On the trolley 3 is a sheave 4, over which runs a rope 5, which passes over a fixed sheave 6 near the point of suspension w. On one end of the rope 5 1s Serial No. 169,838. (No model-l suspended the load L, and at the other end is applied thev power P. With tl16:p&1l5S as indicated in Fig. 1 when 1 descends to the position seen in Fig. 2 the trolley 3 moves to the right-hand or inner end of the trackbeam andthe left-hand or outer end of said beam is lifted, as clearly seen in the lastnamed figure. Now if the load be detached and the power removed the beam will descend and by its weight draw the unloaded trolley back to the other orsouter end of the beam again.

Referring now to Fig. 3, which illustrates a practical application of the invention to a mechanism for. hoisting and transferring loads of varying weights, the same-reference characters areemployed as in Figs. 1 and 2; but in Fig. 3 P designates any suitable Windlass or hoisting-drum, and B designates a frictionbrake carried by the track-beam and adapted to clamplon the fall 2 of the tackle 2. This brake may be of any known kind; but, as shown in detail in Fig. 5, it consists specifically of a fixed corrugated jaw 7, fixed on the track-beam, and a movable corrugated jaw 7 carried by an operating-lever 8, fulcrumed in links 9 on the fixed jaw 7. The-brake is actuated by a pendent rope 10 from the lever 8.

The operation is as follows: The workman W hooks on the load L, sets the brake B, and signals the engineer to hoist. When the load shall have reached the proper elevation. the workman releases the brake, and the trolley moves along the track-beam to the right in Fig. 3, and simultaneously the track-beam is elevated at its outer end, as seen in dotted lines. but before detaching it and setting free the winding-drum the workman sets the brake B on the rope 2. After the load is detached the weight of the track-beam in descending to its normal position draws the trolley again to the outer end of the beam to receive another load'; but this movement should be controlled by the brake in order that the trolley may not move too fast.

The brake B may be dispensed with in cases where the loads are uniform in weight, as the beam may be so weighted as to permit the load to rise to the trolley and come to a stop The load is now lowered and detached;

against it before the trolley begins its moveinent in along the beam.

Fig. 4 shows an arrangement of the device seen in Fig. 3, but wherein the load is hoisted at the inner or pivotal end of the track-beam and transferred to a point under the outer end thereof, or, in other words, wherein the trolley moves along the beam with its lead in a direction opposite to that seen in Fig. 3. In this arrangement it is only necessary to lead the hoisting rope 5 from the guidesheave 6 out and over a guide sheave 12 at the suspension-point 3/ and then back over the sheave 4 of the trolley and to lead the fall 2* of the tackle into and about a guide-sheave 13 on the inner end of the trackbeam and then connect it with the trolley. The operation is precisely the same as that above described, except that the trolley moves with its load in the opposite direction. In both cases the hoisting or lifting of the outer end of the beam 1 serves to store up energ i to return the empty trolley-that is, the travel'of the loaded trolley lifts the end of the beam and in descending the beam shifts the empty trolley back to its normal position.

In Fig. 7, C is a car on a track T, carrying the load L. This car is not hoisted, but is pushed onto the beam 1, up against the trolley 3 thereon, which latter is coupled to the rope 5, leading over a guide-sheave 11 to the hoisting-drum P. In this, view D designates the dump. The operation is the same in sul stance as before explained. WVhen the loaded car is moved onto the beam 1 and coupled onto the trolley, as seen in Fig. 8, and the drum 1 is set in motion, the trolley and car move over to the dump and the end of the track-bean'i at the right in F 7 is hoisted or lifted by the tackle, as il'idicated in dotted lines in Fig. 7, the beam turning about a pivot then uncoupled and run back for another load.

By the word trolley, as herein used to designate the carriage or device for transferring the load, is meant any form or kind of device suitable for the purpose.

Having thus described my invention, 1 claim- 1. Means for the purpose specified, comprisinga movable track-beam, a trolley movable therealong, means for inoving the trolley along the beam with the load, tackle for lifting the beam, said tackle being coupled to the trolley, whereby the latter, in moving to the discharging-point lifts the beam, and a brake which controls the movement of the trolley.

2. Means for the purpose specified, comprising a movable track-beam, a trolley movable therealong, means for moving the trolley along the beam with the load, tackle for lifting the beam, said tackle having its fall coupled to the trolley, whereby the latter, when moving with the load to the discharging-point lifts the beam, and a brake which grips on said tackle-fall to prevent the too rapid return of the trolley.

In witness whereof I. have hereunto signed my name, this 6th day of August, 1903, in the presence of two subscribing witnesses.
